A case of mucous gland adenoma arising from the main bronchus of the middle lobe of the right lung is reported, with review of related literatures. The patient, a 12 year-old Korean male, was admitted to Pusan National University Hospital with complaints of progressive coughing and dyspnea. Roentgenographic studies revealed a well defined mass involving the right middle lobe of the lung. With the impression of benign tumor, right middle lobectomy was performed. The gross specimen revealed a polypoid mass involving the main bronchus, measuring 4.5x 3.7 x 2.5cm. The cut surface of the mass revealed yellow-gray myxoid tissue. Histologically, the mass consisted of glandular structures filled with mucus, which proved to be acid one on histochemical study. The glandular lining was made up of a single layer of berign mucous cells, many of them being flattened.

Extramammary Paget's disease is a dermatosis which pathologically and clinically resembles Paget's disease of the breast. The disease occurs in regions with apocrine gIands; most often in the anogenital area, seldom in the axilla. umbilicus, mucous membrane of the mouth, nose, ear and Moll's gland of tne eyelid. In this work the effect of bleomycin for extramammary Paget's disease was studied on ultrastructural aspect. The material was a case of extramammary Paget's disease of 7 years standing occuring in the scrotum and the pubic area by serial sections after IV injection of 60mg, 120mg and 240mg of bleomycin, and examined under the electron microscope. The results obtained are summarized as follows: 1. The size of Paget's cell and its nucleus was gradually decreased. 2. The numbers of lysosome, dense body, autophagic vacuolization and tonofilament was decreased. From these fidings, it is suggested that bleomycin induces retrograde degenerative change of Pagct's cell, and cell necrosis finally.

We have recently experienced a clinically atypical case of malignant histiocytosis involving the spleen, ileum and bone marrow, in a 25-year-old Korean male. He was admitted to our hospital because of multiple purpuric lesions of skin which had been appearing since 2 years ago. Physical and laboratory examinations revealed marked splenomegaly with pancytopenia. With clinical impression of hypersplenism, splenectomy was performed. During the operation, the surgeons found a dark red mucosal lesion in the ileum incidentally, to resect the segment. Microscopic findings of the spleen and the ileal lesion showed extensive proliferation of atypical histiocytes, many of them phagocytosing numerous erythrocytes. Bone marrow biopsy was done for follow-up study, which showed increased cellularity with infiltration of atypical histiocytes.

PURPOSE: The purpose of this study was to identify factors influencing life satisfaction for mothers with children in elementary school. METHODS: Participants were 243 mothers with a child in first and fifth degree of one elementary school in G city. Data were collected from March 20 to April 9, 2010. The instruments used were Satisfaction with Life Scale, Parent Satisfaction Scale, Korean ADHD Rating Scale, Parenting Alliance Inventory and Scale for Measuring Family Strengths. The data were analyzed using SPSS/WIN 14.0 computer program and included one-way ANOVA, Scheffe back-testing, Pearson's correlation coefficients and stepwise multiple regression. RESULTS: The life satisfaction of the mothers showed significantly positive correlations with parent role satisfaction, spousal support, and family strengths and negative correlations with ADHD. Significant predictors of life satisfaction for mothers with children in elementary school were spousal support and sharing of value systems, and these variables explained 37.0% of the variance in life satisfaction. CONCLUSION: The results of this study indicate that improvement of spousal support and sharing of the family value system should be helpful in promoting life satisfaction for mothers with children in elementary school.

Lymphomatoid papulosis is an enigmatic disease entity which is clinically benign and histologically malignant. Although sporadic cases have been reported, we could not find any comprehensive report on the combined clinical and histologic features of lymphomatoid papulosis in the literature. Perhaps the most controversial aspect of lymphomatoid papulosis is its pathogenesis and categorization as a benign versus a malignant entity. To date, there are no reports on p53 and bcl-2 protein expression in lymphomatoid papulosis. We analysed the clinico-pathological findings of 18 cases with lymphomatoid papulosis during the 10 year period from 1984 to 1995 and examined the prevalence of immunoreactivity for CD30(DAKO, Ber-H2), p53(DAKO, DO-7), and bcl-2(DAKO, 124) using an immunohistochemical(ABC) method. The results obtained are summarized as follows. 1) Age distribution ranged from 20 to 65, with a mean age of 45 years and a sex distribution which showed a male predominence(8:1). The lesions were located on the trunk and extremities(8cases), extremities (7cases), and trunk(3 cases). The morphology of the lesions were papules or plaques(12 cases), and nodules(6 cases). 2) Histopathologic types were classified into 3 types: type A(4 cases), type B(8 cases) and mixed type (6 cases). 3) Positive immunoreactivity for CD30 was seen in 17%(3 of 18cases): type A(2 of 3) and mixed type(1 of 3). 4) The positive immunoreactivity for p53 and bcl-2 was observed in 29%(5 of 18) and 11%(2 of 18), respectively. 5) Cases showing positive immunoreactivity for P53 were type A(1 of 5), type B(1 of 5), and mixed type(3 of 5). 6) Cases showing positive immunoreactivity for bcl-2 were mixed type(2 of 2). One case developed into Ki-1 lymphoma. These results support the idea that lymphomatoid papulosis and Ki-1 lymphoma represent a continuum. The role of p53 gene mutation and bcl-2 activation in the development of lymphomatoid papulosis is currently unknown. But, our results suggest that p53 gene mutation and bcl-2 activation are not a critical step in the development of lymphomatoid papulosis. Further studies are needed to elucidate the role of p53 gene mutation and bcl-2 activation in the development and progression of lymphomatoid papulosis.

Kigelia africana (Lam.) Benth. (Bignoniaceae) is a flowering plants in South, Central and West Africa and commonly known as the sausage tree (Eng.); worsboom (Afr.); umVunguta, umFongothi (Zulu); Modukguhlu (North Sotho); Muvevha (Venda). The dried, powdered fruits are used as dressing for wounds and ulcers, haemorrhoids, rheumatism, purgative, skin-firming, lactation in breast-feeding mothers. The aim of this study is to investigate the cytotoxic and apoptotic potentials of 70% ethanolic extracts of Kigelia africana fruits in HCT116 human colon cancer cells. Treatment of Kigelia africana fruits with various concentrations resulted in a sequence of characteristic of apoptosis, including loss of cell viability and morphological changes. Flow cytometry analysis showed Kigelia africana fruits increased the sub-G1 phase (apoptosis) population. Apoptosis confirmed by annexin V-fluorescein isothiocyanate and propidium iodide double staining in HCT116 human colon cancer cell lines. Moreover, analysis of the mechanism indicated that Kigelia africana fruits showed an increased Bax and Bcl-2 expressions in a dose-dependent manner, resulting in activation of hallmarks of apoptotic events, caspase-3, caspase-9 and cleaved poly-ADP-ribose polymerase. This is the first report to demonstrate the cytotoxicity of Kigelia africana fruits on HCT116 human colon cancer cells.

Moringa oleifera Lam (M. oleifera, Moringaceae) is a tree of the Moringaceae family that can reach a height of between 5 and 10 m. The current paper presents cytotoxic effect of M. oleifera fruits and its flavonoids 1 and 2. The viability of HCT116 human colon cancer cells were 38.5% reduced by 150 µg/mL of ethanolic extracts in a concentration-dependent manner; in addition, we observed the apoptotic features of cell shrinkage and decreased cell size. Bcl-2 family proteins were regulated as determined by Western blotting analysis, suggesting that M. oleifera fruits and their flavonoids 1 and 2 induced apoptosis through an intrinsic pathway. Based on our findings, 70% ethanolic extracts of M. oleifera fruits and flavonoids 1 and 2 might be useful as cytotoxic agents in colorectal cancer therapy.

The incidence of fetal cardiac arrhythmia is approximately 1-3%. Sustatined fetal tachyarrhythmia may cause fetal hydrops and rnay lead to fetal death. We experienced a case of fetal atrial flutter without fetal hydrops at 34 weeks of gestation, which was diagnosed by fetal echocardiography. Transplacental fetal therapy with maternal digoxin administration resulted in restoration of normal fetal sinus rhythm. At birth, the infant showed normal electrocardiographic finding with normal Apgar scores.
